SPECIFICATION forming part of Letters PatentNo'. 605,312, dated June 7,1898.

Application in May 26,1897.

To all whom it, may concern:

Be it known that I, ROCH R. GAREAU, a citi zen of the United States,residing at Detroit,- in the county of Wayne and State of Michi gan,have invented certain new'and useful Improvements'in Indicators, ofwhich the fol, lowing is a specification, reference being had therein tothe accompanying drawings.

My invention refers, broadly, to means for indicating and specificallyto the application of my invention to indicators of the charac-. terused to indicate the presence, absence, or whereabouts of the occupantof the roomin a clock-dial with hour and minute hands is used toindicate the hour of return, together with other indicating devices forimparting further information as to the day of return, number of theoccupants room, the floor of the room, the

To this end my invention consists in the construction, arrangement, andcombination of parts, as more fully hereinafter described, and shown inthe drawings, in which Figure l is an elevation of an indicatorembodyingmy invention; Fig. 2 is a .rear elevation of the operating partsinclosed within" the casing. Fig. 3-is a perspective view of theindicator, showing the curtain across the front face. Fig. 4Eis across-section on the axis of the hour and minute hands.

A is the outer casing of the boX inclosing and supporting the operatingparts of my device.

B is the clock-dial.

C and D" are the hour and minute hands.-

E is an opening in the clock-dial, displayformer inscribed with the daysof the week around its periphery and the latter being marked at itsperiphery with A.M., Pl/L, and the names of such places to which theoccupant of the office usually resorts. Below the dial is a base-plateH, provided with openings I and J, behind which are mounted a series ofnumbered rollers, those in the openin g I by their combinationindicating the numindicating the floor of the occupants room. Theindicator-hands G and D are fastened upon hollow shafts K and L and areprovided panel to hide the dial.

with a device for setting the same by hand serial no. 638. 186. (Nomodel.)

which is operated by a turn-button B in the upper left-hand oorn'erinany suitablemanner.

1 The device shown in the drawings comprises the motor-wheels?) and c,the formergbeing onthe end of the shaft connectedto the turnbutton B andthe latter on the hollow shaft cl, which imparts motion through a, smallcrown-wheel e to a gear-wheel f on a shaft of the minute-hand, which inturn permits the motion through suitable intermediate gearing to theshaft of thehourhand, all soarranged that in turning the button Bi bothhands will be, moved in the proper ratio.

- The rollers FT and G- are sleeved upon a common shaft, and each isprovided with means. for turning the same, which means are actuated bythe push-buttons O and D in any suitable manner.

In the drawings the rollers F and G are shown provided withratchet-wheels and actuating-pawls Z m, against which push-but tons Oand D are adapted to operate in such manner that at each push of thebutton the actuating-pawl will return the roller the'necessary distanceto move a new indication into the opening in the dial, and 'n n arepawls which retain the rollers in their adjusted position.

- The series of rollers in the openings I and J are adjusted by hand,and suitable retainin g-pawls 0, engaging the ratchet-wheels upon therollers, maintain them in position.

The casing in front of the dial is provided with a hinged closing doorF, on the inside of which is mounted in suitable vertical bearings thespring -roller curtain N, which is made of transparent material and uponwhich is marked Present, all so arranged that said curtain may be drawnacross the glass The shaft of the minutehand is hollow, and throughwhich projects a hollow post P, which forms the support for a miniatureelectric lamp A, the electric conductors'for which extend through thehollow .posti'f This lamp is controlled by a suitable snap-switch 4",which is preferably mounted in the remaining corner of the clockdialface.

In practice, the parts being constructed and arranged as shown, theindicator is intended to operate as follows: The name of theperson whichthe indicator is to represent "is indicated in the space S. If absent,his time of return is indicated by the adjustment of the hands, the dayon which he returns on the roller F; if theforenoon or afternoon by theroller G. If engaged in any public building on business, he may adjustthe roller G to denote where he is to be found. When the occupantispresent in his office, he draws the curtain across the closed panel andthereby hides the indications, except those giving his name, number ofroom, and the floor of the building, which appear below the curtain. v

The electric lamp, being suitably supplied with current from a source ofelectricity, which may be furnished on account of the smallness of thelamp by an electric battery contained within the casing, will serve atnight-time to illuminate the whole face of the dial and make all theindications on the face of the device easily readable. At the same time,when the curtain is across, the transparent nature of the curtain willmake the inscription thereon readable from the outside, and thus mydevice is equally "serviceable at all times.

What I claim as my invention is-- 1. The combination with a dial and thehour and minute hands thereof, of hollow arbors carrying the hands, ahollow tube stationarily secured Within said arbors, an incandescentlamp supported by said tube and an electric conductor connecting saidlamp with the sourceof electricity, and a switch for controlling thelamp.

2. In an indicator, the combination of the frame or casing, a clock-dialprovided with indicator-hands and with openings in the dialindicator,rollers in said opening, and setting devices for said indicator-handsand rollers operated by buttons locatedon the face of the dial inproximity thereto, a miniature electric lamp mounted on the clock-facein the axial center of the indicator-hands and a transparent curtainsupported in front of the clockdial.

3. In an indicator, the combination with a primary indicating means, anda light therefor, of a supplemental indicator movably held in relationto the primary indicator and arranged in front thereof and of the lightand adapted to be moved toexpose the primary indicator, substantially asdescribed.

4. In an indicator, the combination with a clock-dial, ofindicating-hands, mechanism for imparting to said hands the properrelative movement provided with an operating device located in front ofthe clock-dial, an indicating-roll mounted in proximity to said dial andadapted to be seen through the latter, and means in front of the dialfor setting said roller, substantially as described.

5. In an indicator, the combination with a clock-dial, and index-hands,of hollow arbors for the hands, means for rotating said arbors to impartthe proper relative movements to the hands, an electric light located atthe front or outer end of the arbors, and a support and conductors forthe light passing through said arbors.

6. The combination with a clock-dial and the hour and minute handsthereof, of a hollow arbor carrying the minute-hand, electric conductorspassing through said hollow arbor, and an incandescent lamp connected toand supported by said conductors in the center of the dial independentof the minute hand and its arbor, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

ROCH R. GAREAU.
